    Abstract: A method for producing a scattered radiation grid or collimator which, for an incident radiation type, has transmissive regions and nontransmissive regions of predeterminable geometry. First the geometry of the transmissive and the nontransmissive regions of the scattered radiation grid or collimator is set. On the basis of this geometry, a base body is constructed according to the geometry, optionally differing by a particular layer thickness, of the transmissive regions or the nontransmissive regions by a rapid prototyping technique through layer-wise solidification of a structural material under the action of radiation. On the basis of this base body, the scattered radiation grid or collimator is finally completed.

    Abstract: A method for assisting in navigation of a medical instrument such as a catheter inside a hollow body such as a vascular system based on a dataset provided by a sensor device of the medical instrument is provided The method includes determining, by a control device, an internal extent of the hollow body based on the provided dataset and determining, by the control device, a navigation path for an impending movement of the medical instrument through the hollow body based on the determined internal extent. The control device is able to generate a control signal that describes a movement along the navigation path.

    Abstract: In a method and apparatus to generate a mammographic image, the apparatus has a radiation source, a digital radiation detector, and support plate and a compression plate between which the breast is compressed during image acquisition. A first image data set depicting the breast is acquired, with a first degree of compression of the breast. A second degree of compression of the breast is set and a second image data set depicting the breast is acquired. The first and second image data sets are linked for the generation of the diagnostic image.

    Abstract: A method is disclosed for reconstructing a tomographic representation of an object from projection data off a moving radiation source through this object onto a detector, filtering and back projection of the projection data being executed in the reconstruction. In an embodiment of the method, by using at least one identical spatial arrangement of the radiation source, the detector and a test object instead of the object to be scanned, there is determined by test projections and an iterative reconstruction technique, a filter that in the given arrangement results in an optimum filtering and back projection of the projection data of the test object for the tomographic representation. Further, the object is scanned instead of the test object in the given arrangement and projection data are determined. Finally, the reconstruction of the tomographic representation is carried out using these projection data and the filter determined. Moreover, an embodiment of a tomography unit for carrying out this method is also disclosed.
